SNMP is a member of the TCP/IP protocol suite. SNMP V1, V2 and V3 are supported on the Delta switch, and it’s enabled by default.
Delta switch supports standard public MIBs for standard functionality and private MIBs that provide additional functionality. You can use SNMP to enable or disable authentication traps, cold-start and warm-start functionality traps, link up and link down traps, Spanning Tree Protocol (STP) traps, SFP traps, password and IP address change traps. IMPORTANT : Make sure that you save the configuration in the Save Configuration page after you have applied the configuration changes. (Save Config Save Configuration) If you don’t save the configuration, then the configuration will be cleared after the switch is rebooted.
3.2.1 SNMP V1/V2 SNMP version 1 (SNMPv1) is the initial implementation of the SNMP protocol. The authentication of clients is performed by a "community string", like a type of password, which is transmitted in clear text. SNMPv2 revises version 1 and includes improvements of performance, security, confidentiality, and manager-to-manager communications. It adds a GetBulkRequest command; it sends iterative GetNextRequests for retrieving large amounts of management data in a single request. 3-35
